The very high need for personal protective equipment (PPE) impacts the waste generated after using these tools. Therefore, to deal with mask waste during the COVID-19 pandemic, this study was carried out on the processing of mask waste using a thermal process and studied how the potential of this process was for the effectiveness of mask waste processing during the pandemic. This research was conducted on Honeymoon Beach by collecting data on mask waste generated during the pandemic, then measuring the waste proximate, ultimate, and calorific value and testing the thermal process using TGA and Piro GC-MS measurements. Most waste masks found on Honeymoon Beach are non-reusable masks, 94.74%, while reusable masks are 5.26%. The waste is then subjected to thermal processing and analysis using TGA and Piro GC-MS. Based on the data obtained, the thermal process can reduce the mass of non-reusable and reusable mask samples by 99.236% and 88.401%, respectively. The results of the Piro GC-MS analysis show that the lit mask waste will produce fragments of compounds that can be reused as fuel. The process is simple and easy and produces residues that can be reused to reduce environmental pollution due to waste generation during the COVID-19 pandemic.

W artykule przedstawiono koncepcję zastosowania skanerów w inżynierii odwrotnej do projektowania i konstrukcji środków ochrony indywidualnej wymagających ścisłego dopasowania do osobnika, w tym przypadku butów oraz masek i półmasek. Przedstawiono modele stóp i twarzy, z których do tej pory korzystano oraz metodologię postępowania z użyciem opisywanych skanerów.

This article presents the idea of using scanners m reverse engineering for constructing personal protective equipment that requires a precise fit to the person, in this case for shoes and masks and half-masks. It presents models of feet and faces, which have been used so far, and the methodology of designing with the use of scanners.
